APPARATUS FOR EVAPORATING AND CONDENSING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 389,075, dated Eeptemloer 4, 1888.

Application filed June 21, 1888. Serial No. 277,754. (No model.)

To aZZ whom it may concern:

Be it known that LJOHN J. HAYES,OfBIOOl lyn, (Green Point,) in the county of Kings and State of NewYork, haveinvented an Improve meut in Apparatus for Evaporating and Con- (lensing Liquids; and the following is declared to be a description of the same.

My invention relates to improvements in apparatus for evaporating and condensing liquids; and the same consists in the combination, with a cylindrical case having diaphragms dividing the case into chambers and forming a central steam'heating chamber, and end chambers for liquid, and pairs of external and internal circulatingpipes passing through the central heating-chamber and diaphragms, of a coil of pipe for steam in the lower chamber, whose respective ends open within the central steam-chan'ibcr and outside of the cylindrical case, a pipe for admitting liquid to the case and discharging the same, and novel means for connecting and supporting the inner cir culating-pipes within the outer pipes.

In the drawings, Figure 1 is a vertical section of my improved apparatus. Fig. 2 is a crosssection at the line :0 w of Fig. 1. Fig. 3 is a vertical section, in larger size, of an outer and an inner circulating-tube; and Fig. 4 is an inverted sectional plan of the inner tube and of the device for securing the inner to the outer tube.

The cylindrical case forming the shell of the apparatus is composed of the portions a a, the curved bottom portion,b,and the curved upper portion, 1). c is a deflector connected to the curved upper portion within the case, and d adischarge-funnel rising from the curved upper portion, 1). The apparatus is divided by two diaphragms, c e, which pass entirely across the case, the diaphragm 6 being between the portions a a of the case and the diaphragm 0 between the portion a and the curved bottom portion, I). There are flanges, as shown in Fig. 1, on these portions of the case, between which the diaphragms e e are securely riveted. Between the diaphragms e 0 there is a chamber formed at e, and there is a chamber or apartment above the diaphragm c and one below the diaphragm e. A gage, g, of usual construction, is connected to the lower and upper portions of the case to indicate the height of the liquid that is within the case,

and a pipe, f, is connected to the curved bot tom portion, 3), through which the liquid to be evaporated and condensed is conducted into the-cylindrical case, and from which the liquid is also passed after being operated upon. A pipe, h, is connected to and passes through the cupved bottom portion, 1), and said pipe is bent to form a coil, h, within the lower chamber of the case, the upper end of said pipe opening through the diaphragm 6, thus giving access to the chamber 6". Through these pipes steam is admitted into the chamber a, said steam filling said pipes and chamber and acting as a heating medium. Pipes i pass through the chamber 0 and through the diaphragms c e, and the ends of said pipes are threaded and secured into openings in said diaphragms, forming a tightjoint where said pipes pass through said diaphragms. \Vithin the pipes 73 are pipes Z of smaller diameter, the upper ends of which rise just above the upper ends of the pipes i, and the lower ends of these pipes Z pass down a considerable distance into the lower chamber of the case. Said pipes Z are clamped in place centrally to the pipes i by clamping-nipples m, that have inclined arms or projections m, these nipples being internally threaded and the pipes Z extcrnally threaded, said nipples being screwed upon the outside of said pipes and their inclined projections m brought within the open ings in the ends of the pipes i, so that their inclined edges touch the pipes and secure the pipes Z, and yet leave an inlet and outlet passage between the interior of the pipes 71 and the exterior of the pipes I.

The liquid to be evaporated or condensed passes within the case by the pipe 1 into the lower chamber, rises within and through the pipes z and partially fills the chamber above the diaphragm e. The steam, which passes into the case by the pipes h and h and fills the chamber 6, heats the liquid in the lower cham her around the coil of pipe h and the liquid in the pipes t, and the circulation upward of said liquid is thus caused through said pipes 2' into the chamber above the diaphragm e, the cooler liquid descending from the upper cham her through the central pipes, Z, down into the lower portion of the chamber below the diaphragm c, a constant circulation being thus maintained up the pipes 'i and down the pipes Z, and the vapors from the liquid, being evaporated and condensed, rise and collect upon the deflector c, and, condensing there, fall back into the liquid below, the heated vapor passing away by the funnel d. There is a sighthole, 0, having a glass through which the operation of evaporating and condensing of the liquid can be seen; and g is a gage which indicates at all times the height of the liquid in the vessel, the same falling with the evaporating and condensing operation. When the liquid is sufficiently evaporated and condensed, the same can be drawn away by the pipe f and the case refilled for another operation.

It will be apparent that the operation of this apparatus can be in a measure reversed as follows: Through the pipes h h and into the chamber 6 a cooling-mixture can be passed, and through the pipefinto the lower chamber, and through the pipes 12 and Z, and into the upper portion above the diaphragm e a heated liquid can be passed that it is desired to cool, the operation otherwise being the same.

I claim as my invention 1. The apparatus herein described for evaporating and condensing liquids, composed of a cylindrical case, diaphragms dividing said case into chambers, pipes passing through said diaphragms and one of the chambers and to said diaphragms centrally, pipes through the forinerpipes, and clamping-nipples having inclined arms or projections, said nipples being secured to the exterior of the internal pipes and having their inclined projections bearing against the ends of the external pipes, so that the internal pipes are kept central and a passage-way is formed for circulating liquid, substantially as set forth.

Signed by me this 18th day of June, 1888.

JOHN J. HAYES.
